LUBBICATING APPARATUS.

' Application led March 14, 1922. Serial No. 548,645.

This invention pertains to improvements in lubricating apparatus and more particularly,v though not exclusively, to improvements in lu ricant supply cups.

y It is among the objects to providea lubricant supply cup which may be conveniently .replenis e with lubricant fromthe lubricant supply apparatus which may, if desired, be of t e type illustrated in my co-pending aplplication, Serial No. 543,-

644, filed herewit of the invention In the drawin s, which show a preferredl form of one em odiment of my invention, and amodification thereof p l Fi relA is a side elevation of a lubricant Su P y CUP- Y ig. 2 is a plan view thereof; l Fig. 3 is a section on the line 3-3 of Fig. 2, being artly in elevation; and 2o shown in Fig.- 3, buttaken through a cup constituting a modification of my invention.

Referring to Figs. 1, 2 and 3 of the drawings and to the preferred form of my invention selected for illustrative purposes, I have shown a lubricant supply cup present- Y ing a body portion 5 adapte to be connected to a part to be lubricated by threads 6, which may be engaged in the tapped holeordinarily used for grease cups, nip les and the Y- like. Cooperating with the bo y 5, I have shown a lubricant-exp lling portion herein typified by the piston Aconnected to a shank 8, which preferably, as illustrated, isexteriorly threaded and engages an interiorly threaded portion of a head 9 carried by the cup 5 and referably permanently connected .thereto as y a spunover portion 10. Cal.- ried by the rshank 8, I have shown a lubricant-receiving nipple 11 which preferably, as illustrated, constitutes the male element of a coupling adapted for cooperation with a source of lubricant under pressure, such, for instance, as the lubricant gun illustrated'in the co-pendin lpplication of Howard J. Murphy, Seri o. 543,649, led herewith. The nipple 11. is connected to the shank 8 with its axis transverse tothe axis of the `shank 8 so that, when thebody 5 is connected to a part to be lubricated, the nipple 1-1 may beturned to point in a plurality of directions so that the lubricant replenishing n or the like may be conveniently connected thereto while the nipple extends the Fig. 4 is a section corresponding to thatv to,- and presents an interior conduit connect-y ing with the conduit 12vpassing throu h the shank 8 to deliver lubricant into t e receptacle or reservoir in the body 5 below or beyond the piston 7. Where, as in the preferred .form of my invention illustrated, the nipple 11 is substantially at right angles to the axis of the shank 8, it forms a convenient handlel therefor so the lubricant in the chamber beneath the piston 7 may be expelled under pressure by merely turning the y shank 8, using the nipple 11 as a handle.

.In the inodcation shown in Fig.l 4, the body portion 13 is exteriorl 4threaded to receive anl interiorly threads lubricant-expelling portion typified bythe ca 14, and the nipple 15 corresponding to t e nipple 11 shownin Fig. 3) is connected to'said cap 14 to extend laterally, preferably above the cap 14 as illustrated, so' that the advantages described in connection with Fig. 3 may in a measure be attained. It will be understood that the ball checks in the nipples 11 and 15 prevent expulsion of grease through the replenishing nipple during thexetion'of pressure on the lubricant by the piston 7 or ca 14.

@Vhile I have described a referred form of m invention and a modi cation thereof, 1t be understood that 'my invention is Abest defined by the following claims.

1. A lubricant supply cup presenting a bod portion for attachment to the part to be ubricated, a lubricant-ex elling portion rotatable relative to said bo y portion and .operable to force lubricant therethrough,

and a relatively long lubricant-receiving nipple carried by said expellin portion and rotatable therewith, said nipp e having its lon 'tudinal 'axis transverse tothe axis of sai expelling portion'whereby the disposition of said n1 ple relative to said body portion may be 'c anged by turning said expel ling portion.

- 2. A lubricant supply cup presenting a body portion for' attachment to a part to be lubricated, a lubricant-expelling portion ro tatable relativeto said body portion to force lubricant therethroih, and a lubricant-receiving ni ple carri by said lling pornipple extending .transversely tion, sai

above said expelling ortion to provide a handle whereby the la ter may be turned.

3. In a lubricating cup, a-body" portion presenting a reservoir, a piston movable in said reservoir to expel the lubricant content thereof and a llubri'cant-receivin nipple for supplying' lubricant .to sai reservoir through said piston', said nipple axially 'transverse to the axis of said piston; thread means operatively interposed between said body portion and iston, said nipple serving as a Ihandle to acilitate turning of said thread means to actuate said piston and also permitting a source of lubricant under pres.

sure to be connected ytherewith from any direction transverse to the axis of the cup.

4. In a lubricating cup', a body presenting a reservoir, a lubricant-expelling piston in said body, a threaded shank for said piston, a head for said body interiorly threaded ,for engagement with said shank and a lubricant-receiving nipple carried by l said shankv on the opposite side of said combination, a body presenting a reservoir,

a piston therein, a shank connected .to said piston, a head for said body through which saidv shank passes, and' a lubricant supply nipple carried by said shankg said nipple and shank presenti communicating conduits for conveying lu ricant to said reservoir be yond said piston, said head permanently secured to said body to preclude loss o'f said piston. l Y

In testimony whereof, I have signed my name to this specification.
